Gears play a major role in power transmission. A precise knowledge of the stresses on gear tooth during operation is very essential in designing a reliable gear transmission system. This paper analyses the stresses on gear tooth, at both tension and compression sides, of the tooth. The analysis of the tooth strength in this paper is based on the distortion energy theory, (Von Mises Theory). A new equation similar to Lewis’s equation was obtained but with a different form factor. The newly derived equation is expected to obtain smaller and hence more economical gears for the same transmitted torque.
